NO such file or directory for files ----- stdarg.h and float.h?

Question

I use some files on the .mm extension in the xcode project to compile these files, we added LLVM-GCC 4.2 in the build setup after adding this compiler that shows an error

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.sdk/usr/include/stdarg.h:4:25: error: stdarg.h: No such file or directory

/Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.sdk/usr/include/float.h:8:24: error: float.h: No such file or directory

I do not know how to remove this error to help resolve this error.

thanks

Answer 1

These headers are not supported in gcc 4.2, which is the default for Mac OSX.

Upgrade to version 4.0 (described here )

Answer 2

I ran into the same problem and couldn't solve the problem with all the other answers here, so I tried:

cd /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/include
sudo mv stdarg.h stdarg.h.original
sudo ln -s /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/gcc/arm-apple-darwin9/4.0.1/include/stdarg.h

!

add additional flags as shown below

CFLAGS += -I"$(YOUR_SYSROOT)/usr/lib/gcc/arm-apple-darwin10/4.2.1/include"
CPPFLAGS += -I"$(YOUR_SYSROOT)/usr/include/c++/4.2.1"
CPPFLAGS += -I"$(YOUR_SYSROOT)/usr/include/c++/4.2.1/armv6-apple-darwin10"
